• If you are trying to use Boolean operators, they must be ALL CAPS: %contributi dalla%((istituto di) OR (((istituti di) OR (istituti pii)))) ((stories critical) OR (sources critical))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%contributi dalla%((istituto di) or (((istituti di) or (istituti pii)))) ((stories critical) OR (sources critical))%22".
• Adding a wildcard symbol may retrieve word variants: %contributi dalla%((istituto di) or (((istituti di) or (istituti pii)))) ((stories critical) OR (sources critical))%22*.
